Cloning Flashcards
define natural cloning in flowering plants
a structure forms which develops into a fully differentiated new plant genetically identical to its parent (asexual reproduction)
where can the new plant during natural cloning be propagated from?
stem
leaf
bud
root
where are undifferentiated cells located in plants?
the meristem
benefits of plant cloning (3)
rapid production of large quantities
same advantageous characteristics
no mating partner needed
negatives of plant cloning (3)
no genetic variety
expensive and requires training
undesirable characteristics are passed on
what is the explant
the cells taken from the plant cuttings/sample
where can a plant sample of cells be taken from?
the meristem tissue from shoot tips or axial buds
why is ethanol used on the plant tissue?
to sterilise it, make sure it is virus free
what is the mass of cells known as produced after placing the explant in plant hormones?
callus (mitosis is stimulated)
